create_category_group

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations confirm write operation (readOnlyHint: false). Description adds no additional behavioral details such as required permissions, name uniqueness constraints, side effects, or error conditions. Bare minimum alignment with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single, efficient sentence with no unnecessary words or fluff. Information is front-loaded clearly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one required parameter and no output schema, the description is minimally adequate. However, it lacks behavioral context and usage guidance, which matters more when sibling tools exist.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% (one parameter 'name' with description). The description does not add meaning beyond the schema; it merely repeats the existence of a name parameter. Baseline 3 is appropriate given high coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the action 'Create' and the resource 'category group', with the purpose 'for organizing budget categories'. Distinguishes from siblings like 'create_category' (different resource) and 'update_category_group' (different action), though the phrase 'organizing budget categories' is somewhat vague.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to create a category group versus using alternatives like 'create_category' or 'update_category_group'. No context provided about prerequisites, typical scenarios, or when this tool is inappropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
